Exemplary embodiments of an interface control method and an electronic device utilizing the same will be described in more detail.

FIG. 1 illustrates one exemplary embodiment of a graphical user interface (GUI) for an electronic device 2. Controlling the electronic device 2 with one-handed (e.g., right-hand) touches can be inconvenient or seriously degrade efficiency for most users, because most users can only touch an area below the dotted line illustrated in FIG. 1.

FIG. 2 illustrates one exemplary embodiment of functional modules of an electronic device 2. Exemplary embodiments of the electronic device 2 may include laptop computers, smart mobile phones, tablet personal computers, and the like. The electronic device 2 includes an interface control system 10, a non-transitory storage system 20, at least one processor 30, and a touch-sensitive display 40. The touch-sensitive display 40 displays and receives touch inputs from a user. An interface control system 10 controls the interface operations on the electronic device 2 in response to touch inputs. Interface or display interface can refer to window, display window, display region, or display area.

The interface control system 10 includes a first detection module 100, a first response module 200, a second detection module 300, a second response module 400, a third detection module 500, a third response module 600, a fourth detection module 700, and a fourth response module 800. The function of each of the modules 100˜800 are executed by one or more processors (e.g. by the processor 30). The non-transitory storage system 20 can store code and data.

The first detection module 100 detects a first predefined user action on the touch-sensitive display 40. The first predefined user action includes, for example, a key press on at least one soft key or on a physical key, or a predefined user gesture.

In the exemplary embodiment, a first predefined user action may be defined by two consecutive actions, such as a first contact with the touch-sensitive display 40 and a movement thereof. Thus, a first predefined user action is detected when a first contact and a motion of the first contact are detected. FIG. 3 illustrates an exemplary embodiment for detecting a first predefined user action, wherein the first detection module 100:

1) detects the first contact and determines whether the position of the first contact is within a predetermined edge area of the touch-sensitive display 40 (e.g., 112);

2) detects the motion of the first contact and determines whether the movement of the first contact is within a predetermined display area 402 of the touch-sensitive display 40.

The first detection module 100 determines whether a first predefined user action is detected when operations 1) and 2) are completed with by a user.

The predetermined edge area of the touch-sensitive display 40 is any area(s) which can be touched by a user's thumb in a one-handed operation. The predetermined edge area of the touch-sensitive display 40 can also be preset by hardware/software, or can be set by users (through, for example, a graphical user interface or hardware interface, both having settings or configuration capabilities).

Wherein when the first predefined user action is detected, the first response module 200, defines a visible cursor (e.g., magnifying glass icon illustrated in FIG. 3) on the touch-sensitive display 40. The initial position of the cursor may be preset to be located at/by an intersection between the path of the first predefined user action and border of the predetermined display area 402. In one exemplary embodiment, referring to FIG. 4, the first response module 200 defines a cursor at a lower-left corner position 126 of the predetermined display area 402 of the touch-sensitive display 40, and the cursor is moved to a third target position 128 according to the user's gesture.

In one exemplary embodiment, the touch-sensitive display 40 may be a pressure touch-sensitive display. The first response module 200 is able to adjust parameters of the cursor (e.g., size, color, velocity, acceleration) according to the amount of pressure on the touch-sensitive display 40.

The second detection module 300 detects a second user action on the touch-sensitive display 40. In the exemplary embodiment, the first predefined user action and the second user action may be defined by two consecutive actions in a single sliding touch operation. Thus, the first response module 200 defines the cursor once the first predefined user action is detected by the first detection module 100. Then the second detection module 300 begins the process of detecting the second user action.

In another exemplary embodiment, the first predefined user action and the second user action may be two separate and independent actions based on a liftoff event (e.g. first user action) and a re-contact event (e.g. second user action).

Wherein when the second user action is detected, the second response module 400 moves the cursor to a first target position (e.g., 122) of the touch-sensitive display 40, and projects a first display area 122A to a temporary-defined one-handed operation area 4022 within reach of the user's thumb. The first display area 122A is located within a predetermined range around the first target position 122. The user can control any function icon or menu of the electronic device 2 by the one-handed operation area 4022. For example, referring to FIG. 3, a soft button 7 in the first display area 122A (hereinafter, SB 7 ¹) is projected into the one-handed operation area 4022. A projection soft button 7 (hereinafter, SB 7 ²), corresponding to SB 7 ¹, is displayed in the one-handed operation area 4022. The user can control an application associated with the SB 7 ¹ through pressing/touching/contacting the SB 7 ². The cursor is moved along the path of the second user action (i.e., the path of the movement of the first contact within the predetermined display area 402). In one exemplary embodiment, the one-handed operation area 4022 may be defined at the same time as the cursor, or may be defined at the end of the second user action.

In one exemplary embodiment, sensitivity of the cursor can be adjusted by users. The cursor can be dragged in a particular direction specified by a vector of the second user action (i.e., finger movement), and having a magnitude proportional to the velocity of movement of the finger.

In one exemplary embodiment, there is at least one software button on the touch-sensitive display 40 which can enable the electronic device 2 to enter into an operation mode (e.g., a moving mode, a zoom-in/zoom-out mode).

In the moving mode, the third detection module 500 detects a third user action, wherein the third action includes a second contact and movement of the second contact, the position of the second contact being located at an edge of the one-handed operation area 4022.

Wherein when the third user action is detected, the third response module 600 moves the cursor to a second target position 124 of the touch-sensitive display 40 and projects a second display area 124A to the one-handed operation area 4022. The projected second display area 124A is located within a predetermined range around the second target position 124.

In one exemplary embodiment, referring to FIG. 5, when the third detection module 500 detects a second contact at a position (e.g., 114) located at the edge of the one-handed operation area 4022, the third response module 600 adjusts the color of the edge of the one-handed operation area 4022. After detecting the second contact at the position 114, the third detection module 500 detects continuing movement of the second contact, and the third response module 600 moves the cursor from the first target position 122 to the second target position 124 according to the path of the movement of the second contact.

In the zoom-in/zoom-out mode, the fourth detection module 700 detects a fourth user action, wherein the fourth action comprises a third contact and movement of the third contact, the position of the second contact being located at an edge of the one-handed operation area 4022.

Wherein when the fourth user action is detected, the fourth response module 800 adjusts display size of objects in user interface in the one-handed operation area 4022.

In an exemplary embodiment, referring to FIGS. 6 and 7, when the fourth detection module 700 detects a third contact at a position (e.g., 116) located at the edge of the one-handed operation area 4022, the fourth response module 800 adjusts the color of the edge of the one-handed operation area 4022. After detecting the third contact at the position 116, the fourth detection module 700 detects continuing movement (inward or outward) of the third contact. The fourth response module 800 adjusts display size of objects in user interface in the one-handed operation area 4022. Referring to area 122B illustrated in FIG. 6, if the fourth response module 800 applies a zoom-in (increasing display size of objects in the user interface in the one-handed operation area 4022), the one-handed operation area 4022 is capable of accommodating a smaller projection area. That is, the one-handed operation area 4022 is capable of accommodating fewer objects in the user interface. A larger display size of objects in the user interface in the one-handed operation area 4022 can be required for visually challenged users. Referring to area 122C illustrated in FIG. 7, if the fourth response module 800 applies a zoom-out (decreasing display size of objects in user interface in the one-handed operation area 4022), the one-handed operation area 4022 is capable of accommodating a larger projection area. That is, the one-handed operation area 4022 can then accommodate more objects in the user interface.

FIG. 8 illustrates a block diagram of another exemplary embodiment of functional modules of an electronic device 4. In the exemplary embodiment, the electronic device 4 includes an interface control system 14, a non-transitory storage system 24, at least one processor 34, and a touch-sensitive display 44. The interface control system 14 includes a first detection module 104, a first response module 204, a second detection module 304, a second response module 404, a third detection module 504, a third response module 604, a fourth detection module 704, and a fourth response module 804. The modules 504-804 correspond to and are similar to the modules 500-800 illustrated in FIG. 2. Modules 104-404 are detailed as follows.

The first detection module 104 detects a first predefined user action on the touch-sensitive display 44.

Wherein when the first predefined user action is detected, the first response module 204 defines a cursor and a one-handed operation area on the touch-sensitive display 44.

The second detection module 304 detects a second user action on the touch-sensitive display 44, the first predefined user action and the second user action may be defined by two consecutive actions in a single sliding touch operation.

Wherein when the second user action is detected, the second response module 404 moves the cursor to a first target position of the touch-sensitive display 44 and projects a first display area to the one-handed operation area. The projected first display area is located within a predetermined range around the first target position.
